IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 144,761, dated November18, 1873; application filed J une 28, 1873.

To all whom it may concern:

Be it known that I,WILLIAM H.HAMMOND, of Syracuse, in the county ofMorgan and State of Missouri, have invented a new and valuableImprovement in Boiler and Steamers; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexeddrawingsmaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a bottom view of theinner basin of my steam-boiler. Fig. 2 is a vertical central section ofmy steam-boiler.

This invention has relation to steam-current guides for wash-boilers,and others; and it consists in the construction and novel arrangement ofthe removable suspended flanged inner basin or chamber, perforatedthrough the upper portion of its wall, when it approaches more closelythe wall of the boiler, and provided on the inside of its bottom withraised crossing plates, under the ends of which are peripheralperforations through said bottom, and, externally, with a dependingchannel-way beneath a central slot through the bottom, above which thebroadest of the internal crossplates is arranged.

In the accompanying drawings, the letter A designates the boiler proper,which may have any of the ordinary forms. B represents the inner basin,flaring in form, and provided at its upper edge with an outwardly-turnedflange, (0, adapted to rest on the upper edge of the boiler proper. Gdesignates a closelyfitting cover, the inner vertical flange b of whichis designed to pass within the upper part of the vessel B, and thehorizontal rim 0 of which rests on the flange a, thus aiding in forminga close joint between the vessels A and B. Through the side wall of theinner vessel B are perforations 6, arranged in a horizontal series alittle distance below the flange a. In the bottom (I of the vessel 13,which, when said vessel is suspended by its flange, will be a shortdistance above the bottom of the vessel A, is the central transverseslot below which is secured the transverse channelguide h,in such amanner that all the water passing downward through said slot will bereceived into said channel-guide and discharged horizontally at its openends, it. This channel-guide h does not extend to the edge of the bottomd on either side, space being left for the perforations l, which aremade through said bottom between the open ends is and said edge. Atninety. degrees distance from the perforations l, at opposite ends of adiameter passing at right angles with the transverse slot 9, are thelarge semicircular apertures m through the bottom d. On the upper orinside face of the bottom 01 are arranged the raised plates 02 a, onebroader than the other, and crossing or secured to each other centrally.These plates are convex or arched in form, and are secured to the bottomd just outside of or beyond the perforations l and m, respectively, thebroader plate at covering the perforations l and the slot 9.

The goods are placed in the inner vessel B, and are kept from theopenings through its bottom (I by the guard-plates n a. A sufficientquantity of water having been placed in the bottom of the vessel A, theboiler is ready for the application of heat. The current is set up bythe action of the steam forcing the water up into the tapering spacebetween the walls of the vessels A and B, and through the perforations0. At the same time a suction is created below by the water passing upby the open ends 70 of the channel-guide h, and the openings 1 ondrawing the water of the vessel B downward through the goods,cen-

trally as well as peripherally, thereby accomplishing a thoroughcleaning.

What I claim as new, and desire to secure by Letters Patent, is-

The suspended inner flanged boiler 13, having at its bottom the centralslot 9, peripheral openings l m, the depending transverse channel-guideit below said slot, and the inside raised plates n a, crossing orsecured to each other centrally, and covering said slot and openings,substantially as specified.

In testimony that I claim the above I have hereunto subscribedv my namein the presence of two witnesses.

WILLIAM HENRY HAMMOND.
